Because of its simplicity, economy, and durability, thein ducti on motor is more widely used for in dustrial purposes tha n any other type of ac motor, especially if a high-speed drive is desired.I

16、f ac power is available, all drives requiri ng con sta nt speed should use squirrel-cage in duct ion or synchronous motors because of their rugged ness and lower cost. Drives requiri ng vary ing speeds, such as fans, blowers, or pumps, may be drive n by woun d-rotor in duct ion motors.However, if th

The squirrel-cage motor is the least expensive ac motor of the three types considered and requires very little control equipment. The woun d-rotor is more expe nsive and requires additi onal sec on dary con trol. The synchronous motor is even more expe nsive and requires a source of dc excitati on, as wel
